St. Landelin, Catholic church in Ettenheim, Germany.

St. Landelin is a single-nave church built in 1687–98 in Ettenheimmünster, with a three-sided choir, a choir flank tower on the north wall and a transept arm added in 1765 to a design by Franz Joseph Salzmann. Inside, a barrel vault with stucco panels rests on wall pillars, and the nave is lined with dark wooden pews along a broad aisle of large diagonal stone tiles. The raised sanctuary holds a white altar with a gold tabernacle beneath an ornate reredos of dark columns, gold scrollwork and a central painting; two dark side altars with gold detailing, each with a crucifix and candles, stand against the side walls, and a ceiling fresco framed by an arched border fills the vault.

St. Landelin was built in 1687–98 as a single-nave church with a recessed, three-sided choir and a choir flank tower on the north wall. In 1765 a transept arm by Franz Joseph Salzmann was added to the south side of the choir. The church was a pilgrimage church of Ettenheimmünster Abbey before becoming the parish church of Ettenheimmünster.

St. Landelin began as a pilgrimage church of Ettenheimmünster Abbey and is now the parish church of Ettenheimmünster, a district of Ettenheim. The Landelinsquelle spring is enclosed in a fountain house on the west side of the building, and a reliquary with the bust of Landelin of Ettenheimmünster was made in 1506. Four confessionals came from the former abbey church.

The church stands in Ettenheimmünster, a district of Ettenheim in the Ortenaukreis. The Landelinsquelle spring is enclosed in a fountain house on the west side of the building, so the west end is the natural starting point for a visit. The nave is entered from the west; the choir with the 1765 transept arm lies to the east.

Inside the church hangs a small bell that is the only survivor of a seven-bell peal cast in the 18th century by the Strasbourg founder Edel. The four bells in the tower today were cast in bronze by Friedrich Wilhelm Schilling in 1954; the largest strikes the hours, the next two the quarter-hours.
